Official Title: Phase I Trial of Super-Selective Intraarterial Cerebral Infusion of Cetuximab (Erbitux) for Treatment of Relapsed/Refractory Glioblastoma Multiforme and Anaplastic Astrocytoma

Brief Summary: The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. One currently used drug called, Cetuximab (Erbitux) has been shown to be active in human brain tumors but its actual CNS penetration is unknown. This phase I clinical research trial will test the hypothesis that Cetuximab can be safely used by direct intracranial superselective intraarterial infusion up to a dose of 500mg/m2 to ultimately enhance survival of patients with relapsed/refractory GBM/AA. By achieving the aims of this study the investigators will determine the the toxicity profile and maximum tolerated dose (MTD) of SIACI Cetuximab. The investigators expect that this study will provide important information regarding the utility of SIACI Cetuximab therapy for malignant glioma, and may alter the way these drugs are delivered to the investigators patients in the near future.

Detailed Summary:

There is no current standard of care for recurring GBM after patients receive Bevacizumab (Avastin) intravenously (IV) at 10mg/kg with CPT-11 (Irinotecan). At that point, these patients are deemed treatment failures and are given another experimental treatment. Because of the blood brain barrier (BBB) where IV drugs do not penetrate the blood vessel walls well to get into the brain, no one knows for sure if these IV drugs actually get into the brain after infusion. Previous studies have shown that if you want to increase your penetration of drug to the brain, that intra-carotid artery (intraarterial) delivery is superior to standard intravenous delivery. Previous techniques using intraarterial (intracarotid) infusion still were non-selective as drug delivery still went to all blood vessels in the brain, so patients still had significant adverse events, such as blindness. Newer techniques in interventional neuroradiology have allowed for a more selective delivery of catheters higher up into the arterial tree where agents such as chemotherapies, can be delivered without the risk of adverse affects such as blindness. In fact, studies here at Cornell have developed very new and exciting super selective intraarterial delivery treatments for Retinoblastoma, eye tumors with little toxicity and a clinical trial of intraarterial delivery of Avastin is currently underway for GBM. Therefore, this trial will ask one simple question: Is it safe to deliver a dose of Cetuximab intraarterially using these super selective delivery techniques instead of the standard intravenous route of administration? This should not only increase the amount of drug that gets to the tumor but also spare the patient any adverse effects from a less selective delivery. Prior to that single dose of intraarterial Cetuximab, the patient will also receive a dose of mannitol that opens up the blood brain barrier to improve delivery of the agent to the brain. Aft
